Installing the Input Cables
RECOMMENDED USE OF
AUXILIARY BATTERY.
Ground
FUSE
In order to install the power supply, Use the appropriate cable as specified for the model chosen. The
positive cable should come straight from the battery and have a fuse or protective breaker 30 cm from the
battery. The negative cable should have the same gauge as the positive cable and be screwed to the chassis
of the vehicle, being careful to avoid paint and rust. These may interfere with the flow of the electrical
current and cause loss of power and interference in the sound.
REMOTE
(REM)
SPEAKER (OUTPUT):
This output is MONO. Be careful of maintaining the correct polarity of the
connections between the speakers and check the minimum impedance of this output. Use cables with
minimum gauge as specified for the purchased model.
VENTS:
Allows for the removal of warm air from the amplifier. In model
DDM5000.1
, this opening has a fan.
POSITIVE POWER SUPPLY :
Connect the terminal to the positive terminal of the battery (+12V).
It is extremely important that a protective fuse or circuit breaker be used on this cable at a distance of
30 cm from the battery. The fuse or circuit breaker should be, at minimum, equal to the max current
consumption value caused by playing musical signals (see technical specifications table).
REM (REMOTE CONTROL):
Connect the
REM
terminal to the electric antenna output of the
receiver or
player
. This will cause the amplifier to turn on automatically when you turn on your receiver or player.
GROUND CONNECTION :
Connect the cable to the chassis of the vehicle.
Note: always connect the
wire of the player or other equipment to the same ground point.
CLIP LED (RED):
This LED will light up when the signal begins to suffer distortion.
PROT LED (RED):
This LED will light up for the following reasons (see the diagnostic table on the back
cover):
A)
Short circuit in the speakers
C)
Low battery voltage
B)
Excessive temperature
D)
High battery voltage
POWER LED (BLUE):
This indicator LED will light up when it is activated by the remote control signal
from the
receiver or player.

ATTENTION:
The use of a the fuse or breaker is required,
since this amplifier has no internal fuses.
